My invention relates to lmprovements in automatic water heaters, and theobject ot my improvements is to construct, a water heaterin compct.form, inexpensive 1n design, and economic in its consumption' ofThisapplieatioii is-aJ divisional application from my application filedJuly 6th 1915, Serial Number 38,381. To the above purposes, my inventionconsists in certainaiovel features of the construction and arrangementof vparts which will be hereinafter specifically described, pointed outin my claim, aiutillustratcd by the accompanying drawings, in which#lFigure is a vertical sectional elevation of the complete water heatingapparatus, and

Fig. 2 is an enlarged plan, partly in section, showing the construction,and arrangement of the water bodies and the damper Referring by numeralsto the accompanying drawings, 7 designates a double w-'alled shell ordrum, between. which double walls water to be heated is circulated, andthrough which shell heat. is directed.

This shell is preferably open hottoincd, and supported above the tlooron a base so that water controllingl and heating,r dei-'ices may beinstalled beneath the shell.

Between the double walls at their upper and lower ends, I insert rings9, which close the ends of the space between said walls. Through theouter ivall nearits bottom l provide a nipple l() and connect therewitha service pipe 11 leading from a source (not shown) of water supplyinitier pressure.

respect it is preferable that the battles be of,

greater water capacity and covera. greater area at the top of the tra-inthan et the' bottom.

To the lowerniost baiile I connect a pipe 13 leading' to a waterbovll.Connected with the. water box is a cylinder 17,A which connnunicateswith the box and in which there is a piston (not shown) connected withthe rock shaft. 15.

In eonnnunierition with pipe 13 is a pipe 19 having a. valve 20 from,which hot water is drawn. -As shown in Fig. 2, each baille is semi-diskshaped and has on its interior awall 20"* extending at an angle from theapproximate longitudinal center of the v:straight sideot' the baffletoward, but notl to,

the opposite round wall of the baiile.

Through theupper` and lower walls of each battle and -on each side ofthe wall 20 there is a. tappedepening into which nipples '2l arethreaded for the connect-ion of thevarious bailles cn. train..

Ort-r the top of the drum or shell 7, I provide a cap 22 and connecttherewith a iin- 22S, which carries oli' the surplus heat after having`passed tlnfongh the shell and conducts it, from the heater in a commoninanncr.

The lue 22' .is provided with a damper 2i, whose shall'. is providedwith a crank l5 for its operation.

The numeral Q13 designates a ,e'as pipe which extends to and beneath theshell 7, whcrcat is secured a reducing nipple '27, and secu-red to thenipple 2T is a cap 12S.
